what is the maximum number of indexes i can create for a
table?
What happens if i create indexes for all the columns of a
table? Will it slow down the speed of retrieval
Answer Posted / surendra
we can create number of indexes we want but these are useful to us to speed up the retreive the records
such as these columns are simultaneously used in where clause
when we create more indexes that are not necessary to us at that time the performance is definitely decreased.
so, create indexes depends upon the usage.
